how to capturing the Moran's I output file names
I am running Global Moran’s I with an iterator (220,000 records grouped by a field called M_GEOID_2, which has 927 different values). What I need to do is change both the output feature class name and the HTML report file name to reflect those groups. The current output features have identical names taken from the input…

Propose renaming "Confidence" via OHSA to "Confidence Int." or "Confidence Interval"
Would Esri be open to renaming “Confidence” to “Confident Interval” or “Confidence Int.” for OHSA results? I realize this could be rectified quickly by the user by simply renaming it within the "Contents" pane. However, I think it's important Esri considers the potential misinterpretation of the OHSA results by designating…

How to create a space time cube with 2 or more variables
Does anyone know how to create a space time cube with 2 or more variables? I am very interested in the newly introduced "Time Series Cross Correlation" tool and it need a space time cube with 2 or more variables as input. I have tried using "Create Space Time Cube From Multidimensional Raster Layer " tool but the result…

Consistency of bandwidth (GWR) between methods
Using ArcGis 10.8 Whe using arcpy.GeographicallyWeightedRegression_stats() or arcpy.stats.GeographicallyWeightedRegression(), the bandwidth obtained is different than those equivalents obtained trough R software (spgwr AND GWmodel), which are consistent between them Reproducible example: using columbus dataset (library…

Forest Based Classification and Regression
I am using 5 rasters in my model to predict a soil property point data. I am wondering what it means when you have a low variance explained 22% (model bag of errors), however in my training data regresssion diagnostics, the R2 is 89% and the SMSE and SE are also low. Also, when I look at my residuals the model appears to…

Moran's I significant only when using 'Inverse Distance' conceptualization
For a points file, I used 'conceptualization of spatial distance' for Moran's I as: 1 - Zone of indifference 2 - Inverse distance 3 - Inverse distance squared The Moran's I was statistically significant only for 'inverse distance'. Subsquently I used hot spot analysis and found statistically significant hot and cold spots.…

Kriged surface showing different scale
I have data points (points shapefile) on the proportion of a certain disease, with values ranging from 0 to 1. After creating a kriged surface, the proportions ranged from 0.043 to 0.756. I need to understand why this discrepancy occurred. For reporting these findings in a scientific journal, would it be appropriate to use…

Kriging: Choice of 'Maximum Distance'
Using point data, I ran Moran’s I with a distance band of 100,000 meters to ensure that each point had at least one neighbor and obtained statistically significant result. Now, when trying to run Kriging, I am unsure whether to use the ‘fixed’ or ‘variable’ option for the ‘Search Radius Settings.’ I am particularly…

Moran's I is not significant on unprojected data but significant on projected data (area less than 30 degrees)
Hi, When analyzing point data spanning about 26 degrees, I obtained a Moran's I value that is not statistically significant. However, after projecting my shapefile, the p-value becomes highly significant. Although the area covered by the points is definitely less than 30 decimal degrees, I'm uncertain about how to proceed.…

Forest based and boosted classification and regression - tool errors
Hi, I'm running a random forest classification using the Spatial Statistics Tool "Forest Based and Boosted Classification and Regression." I have three explanatory 30m rasters (canopy height, canopy layers, large tree density), all of which are numeric. Prediction Type: Predict to raster Model Type: Forest-based Input…

Geographically Weighted Regression difference in Desktop and Pro version
Hi, I am trying to identify a relationship between water demand and land use land form variables. However, when I am working on Residential Landuse (% in each municipal ward/census block) unit vs water demand in Desktop and Pro versions I am getting different R2 values and on the lower end as well. In Pro version, I am…

Geographically and Temporally Regression (GTWR), the p-value of Local regression coefficients
Hi! I have recently been puzzled by the p-values of the local regression coefficients of the GTWR model, which are rarely mentioned in related research publications, where people only report the R-squared, Ajusted R-squared, and AICc of the OLS, GWR, TWR, and GTWR to show how well the models are fitted. However, when the…

Space Time Cube Analysis without 10 time intervals
Good morning! I'm working on an analysis of change over time for populations within an existing polygon shape file. I have 5 years of historical population data per relevant polygon. However, when I run the Create Space Time Cube from Defined Locations, I receive error 110004: A STC must have 10 time slices. Is there a way…

How to represent the results of emerging hotspots?
Excuse me @LaurenGriffin and folks from Esri Spatial Statistics Team, I'm confused about representing the results of Emerging Hot Spot Analysis. I used K Nearest Neighbours with a defined global window 'Neighbourhood Time Step' on accident data over a period of 10 years. I'd like to ask a few questions. First question, the…

Forest-based classification: compensate for sparse categories same as fixing imbalanced datasets?
I have an imbalanced dataset, where the variable to predict is imbalanced (83% of features are non-events compared to 16% of the events). If we were to run forest-based classification in python, for example, we would run a combination of oversampling the events and under-sampling the non-events. The Compensate for Sparse…

Dimension Reduction Tool - First Time Using
Good evening, This is my first time using the Dimension Reduction tool and unfortunately, there really aren't any Esri videos that talk about this tool. So I have census tract level data containing 30 different variables (covering race, age/sex, income, housing, health, total population, education) and I was trying to…

2000 Census Tiger File Conversion
Hello I am a beginner student in learning about ArcGis Pro and I need 2000 Census Data for the state of Louisiana. There seems to be no shape files and it seems like I will have to convert it from a Tiger File to a Shape file. If anyone has any Idea what I could do. It would be a major help. Thanks, Noah

Expose Space Time Cube aggregation (netCDF) bin geometry
After creating a space time cube by building a netCDF structure and aggregating points into hexagons then symbolizing them in a 3d scene, I would like to represent the fishnet or hexagonal geometry used to generate the netCDF so viewers can visualize the binned geometry on the map. Since the aggregation bins are created to…

Multiscale Geographically Weighted Regression Tool: output displayed incorrectly
@EricKrause Hi Eric, I would like to report one possible bug related to the Multiscale Geographically Weighted Regression tool. When using ArcGIS Pro 3.0 or 3.1, if the coefficient value in the output is less than -1.0364, it will not show up in the map. When using ArcGIS Pro 3.2, the output is displayed correctly, notice…
